Summary:

An experimental study is reported in a simplified flow configuration aimed at deriving a correlation for the Nusselt number, which can be used to predict the thermal behavior of intake valves in port-fuel injection systems. The analysis is based on simultaneous measurements of droplets characteristics and surface thermal behavior and is relevant for the period of engine warm up.For the engine operating at steady state, an integral method to describe the overall process of heat transfer is devised, which accounts for the heterogeneities of fluid-dynamic interactions induced by multiple and successive droplet interactions within the area of spray impact. The method considers overall boiling curves dependant on the injection conditions and provides an empirical tool to characterize the heat transfer processes on the impact of pulsed sprays. The information is also useful to the development of models for engine simulation
